Heat Saviour aims to save up to £2,000 on installation costs
Hewer, a heating firm that makes and installs heating technology, has launched ‘Heat Saviour’, a low-carbon technology that could save up to £2,000 when they install heat pumps by cutting down on labour costs.
The product has been designed to be placed underneath a standard hot water cylinder and Stuart Hesk, director, Hewer, said it is to work with all major heat pump brands and is no longer exclusive to one manufacturer.
Heat Saviour also aims to minimise system downtime, as well as have built-in backup heating during maintenance or a pump failure.

Hesk said the reason behind the Heat Saviour launch was because installing and retrofitting heat pumps can be “complex, costly and disruptive”.
He continued: “They are often designed with non-universal parts, requiring entire heating systems to be ripped out, systems that could have years of use left in them.
“Heat Saviour is a much smarter and cheaper way for engineers to install and maintain a heat pump, making property management easier and improving residential satisfaction.”
A further reason behind the creation was to reduce the amount of waste, cost and downtime that installing and retrofitting heat pumps can cause, saving homeowners around £2,000 in installation costs.
The product has cut glycol use by 80%, making them better for the environment, and allows radiator maintenance without the costly expense of having to drain and replace the glycol solution.

Hesk said the unit is ideal for social housing and council projects, as it means homes won’t have to overhaul their entire pipework to make a home “heat pump ready”.
The other benefits include:
Reduces installation time and labour costs – ideal for retrofit programs
Minimises system downtime – essential for keeping tenants warm
Built in backup heating – ensures no loss of heating during maintenance or pump failure
Works with all major heat pump brands
Supports compliance with low-carbon heating initiatives and net zero targets
For installers, Hesk said the benefits are that they use standard off the shelf components, they are pre-engineered and ready to install. It also supports retrofit work in older or mixed heating systems.

He has also written extensively for consumer titles like City AM, The Morning Star, and The Daily Express.
In 2020, he covered in detail the International Maritime Organisation’s (IMO) legislation on sulphur emissions and its effects on the global container shipping market as online editor of Port Technology International.
He also explored the initiatives major container ports and terminals have launched in order to ship vital goods across the world without polluting the environment.
Since then, he has reported heavily on the impact made by environmental, social, and governance (ESG) practices on the supply chain of minerals, with a particular focus on rare earth mining in Africa.
As part of this, in 2022 Max visited mines and ports in Angola to hone in on the challenges being faced by one of the world’s biggest producers of rare earth minerals.
His most recent sustainability-related work came much closer to home, as he investigated the eco-challenges faced by independent retailers in the UK, specifically looking at how they can cut emissions and continue to thrive.
